Patent EP-0536869-A2 (EP)
Inventor: RAMDE AMOLAK
IPC: H01L29/732
Filed: 1992-05-27
Abstract: A P-type buried layer is described for use with planar, silicon, monolithic, epitaxial, PN junction-isolated transistors of PNP conductivity primarily for use in IC construction. The buried layer includes a high concentration of boron and gallium along with germanium, which is in sufficient concentration to inhibit impurity diffusion in the silicon epitaxial layer. This inhibition effect has been found to be sufficient to cause the combination of boron and gallium to act as slow diffusers. The result is comparable to that the performance of arsenic and antimony, in the creation of buried layers for NPN transistors. Thus, the performance of NPN transistors can be matched for PNP transistors. This means that an IC can be fabricated so that more nearly equal performance NPN and PNP transistors can be fabricated simultaneously in a common substrate.

Abstract: A method and apparatus for erasing Flash EP - ROM cells that avoids overerasure is provided. A high - impedance device is placed between the drain of the cell and the high-voltage supply used to erase the cell. As soon as the cell enters the onset of depletion and begins to conduct, most of the high voltage is dropped across the high - impedance de - vice, leaving insufficient potential across the cell for Fowler - Nordheim tunneling to continue. The erase process is thus self - limiting. The process can be used on a chain or array of EPROM cells, with erasure stopping when any one of the cells con - ducts. Bias differences between erase and read modes assure that the cell that first goes into depletion is not in depletion in normal operation.

Abstract: Office furniture units, particularly desks (10), are fabricated of panel members (12,50,54,58,60,66), cut from standard pre-finished flat wood panels, to their precise final configuration, by an NC controlled automatic router, including all holes, recesses and the like required in each panel member. The panel members have configurations which constitute the intelligence to assure their precise alignment as they are subassembled into furniture panel components by securing the appropriate panel members together in multiple layers, and for reception of two-part mechanical fasteners in appropriate positions to insure proper positioning of the panel components with respect to one another in the final assembly of the panel components into a functional office furniture unit. The panel components are assembled with one another in T-joint fashion, with the edge surface of one panel abutting a major side surface of the respective transverse panel to which being joined, using cam-type fastener components which secure the panel components together in firm edge-abutment relationships. The multiple layers of panel members provide reinforcement and rigidity of the panel components where necessary, as well as visual thickness effect. In each instance, one of the panel members is of the configuration of the final panel component. Several of the panel members include edge tabs which protrude laterally of the respective subassembled components for interfitting in recesses provided in mating panels to provide enhanced shear strength across the T-joint interpanel connections in the final assembly of the furniture unit. The structure and method also provide flexibility to produce differing furniture items in successive machining and assembly operations, for rapid production of a variety of different products "to order" from a single machine.

Abstract: A method and apparatus for positioning a magnetic servo head relative to a servo track on a traveling magnetic tape both make use of the observation that a given tape in a given tape drive unit exhibits transverse tape movements during operation which constitute a "signature" waveform for the coupled tape cartridge and drive unit. In the method and apparatus, the transverse movements of a traveling tape in a drive unit are monitored to obtain the aforementioned waveform which is characteristic of the transverse movements for that tape, and the waveform is stored. The positioning of the servo head is controlled relative to a servo track on the tape using a control signal generated according to any known track seek algorithm. The stored waveform is recalled and is superimposed on the control signal, thereby significantly increasing the accuracy of the positioning of the servo head, which in turn increases the accuracy of positioning of the write/read head.

Abstract: A database system for maintaining accounting records in relation to usage of postage meters (10 1 ......10 n ) is disclosed. The database system is provided with two computers (13, 14), both of which provide access to the system from remote postage meters via a telephone network (11,12), and each computer maintains a separate database (15, 16). One computer (13) acts as primary and handles all transactions, received either direct or via the other secondary computer (14), and maintains a primary database (15). For each transaction, the primary computer creates an archived record in a buffer and periodically when the buffer is full sends an archive record to the secondary computer (14) for use by the secondary computer to update the secondary database (16). In addition for critical transactions such as a postage meter recredit transaction, the primary computer also creates a transaction log and sends it to the secondary computer for storing in a FILO buffer. The primary computer lastly authorises credit to the postage meter. In the event the archived record is not sent to the secondary computer due to a fault in the primary computer, the secondary computer utilises the transaction log to update the secondary database with critical accounting data.

Abstract: Data collection devices often have optical transmitters to transfer the stored data. In most cases, read devices cannot be coupled directly to the transmitter during the recording of these data, so that extraneous light impairs the data transfer. The evaluation method and the circuit arrangement to carry out the method are intended to enable signal recording which is largely independent of the effects of interference. For this purpose, the useful signal, with a superimposed noise signal, is first amplified and a derivative signal containing the pulse edges of the useful signal is formed through differentiation and these pulse edges are then separated in a comparator stage (9) according to their polarity and an output signal corresponding to the useful signal is finally generated by means of a downstream memory component (15). The circuit arrangement to carry out the method is particularly suitable for high-speed recording of counter readings with a mobile data recording apparatus. <IMAGE>

Abstract: The present invention provides a multiprocessor system for processing instruction arrays comprising attribute setting instructions and tasks. When an attribute setting instruction is transmitted to the system, it is first written into a first TSL buffer. Then a comparator determines the difference between the corresponding addresses in the first TSL buffer and a second TSL buffer, and a TAG circuit stores the changed parts. When a task, or primitive, is allotted, the contents of the TAG circuit are referenced and only the changed parts are copied from the first to second TSL buffer. Then the second TSL buffer is locked to retain the instantaneous value of the TSL. An MPU performs drawing with reference to the snapshot of the TSL retained by the second TSL buffer. 
     By the above technique a graphic system according to the invention can use a multiprocessor to perform fast parallel processing by efficiently assigning drawing instructions to each node, since a TSL snapshot at any time can be obtained quickly for use.
